Much thanks for all the hard work involved in this detailed cataloging of your instruments! I like...

see placid cam's music to hear an integration of those orchestral samples into a musical snack. The phrases library includes thousands of phrases and articulations played on orchestral instruments. The samples have all been recorded by Philharmonia Orchestra players and are free to download and use, but please note: You can use the samples to create any kind of musical composition, you can even share them with other people, but you cannot sell them. In other words, you have the right to use...

This was especially cool when it started out.

On Saturday, April 29th the artists Ligorano/Reese installed a temporary sculpture in the garden of Jim Kempner Fine Art, located in the Chelsea neighborhood of Manhattan. Sculpted in ice and spelling out the word “Democracy” in block letters, the installation reflected on the current political state and the transience of our cultural values. Measuring 20 inches high and 120 inches in length, the word melted over 24 hours. The sculpture cracked, diminished, and ultimately disappeared,...

Having discussed "heavy weight" virtualization technology in recent weeks, this week Leo and Steve examine "lighter weight" application sandboxing technology and the software solutions currently available to perform this form of application "wrapping." We discuss the inherent limitations of sandbox security and explain how valuable sandboxes can be for privacy enforcement.

Leo and Steve discuss two new 0-day Internet Explorer vulnerabilities (both now being exploited on the Internet); then we explore the commonly expressed privacy and security concerns presented by the need to trust Internet Service Providers (ISP).

Leo and Steve first discuss errata from previous episodes, correcting, among other things, Steve's first poor impression of Vista's performance. Then we discuss the results of my in-depth research into the inner workings of Vista's Kernel Patch Protection (aka PatchGuard) to uncover its limitations, benefits, and real purpose.

Having covered the operation of the Internet's WAN (Wide Area Network) technology in the past two weeks, this week Leo and Steve turn to discussing the way Local Area Networks (LANs) operate and how they interface with the Internet WAN. We address the configuration of subnet masks, default gateways, and DHCP to explain how packets are routed among machines and gateways within a LAN.

Leo and Steve open a multi-week discussion of the operation and technology of cryptography. This first week we start by examining the social consequences and ethical implications of common citizens being empowered with freely available cryptographic technology that no force on Earth — no government agency, no corporation, no private individual — can crack within their lifetimes.

The secondary disk extends at least 24 billion miles from the star and is tilted roughly 4 to 5 degrees from the primary disk. The secondary disk is circumstantial evidence for the existence of a planet in a similarly inclined orbit. The planet may have indirectly formed the secondary disk by sweeping up smaller planetesimals ? chunks of rock and/or ice ?...

The bright blue and green swirls that the Moderate Resolution Imaging Spectroradiometer ( modis.gsfc.nasa.gov MODIS ) detected off the coast of Vancouver Island, Canada, were made by millions of tiny ocean plants called phytoplankton. The coastal waters of the Eastern Pacific are productive because wind and ocean currents allow nutrient-rich water from deep in the ocean to rise to the surface. The cold, rising water carries phosphates and nitrates, which act as fertilizer to the phytoplankton...

In simplest terms, the SSSP is the problem of scheduling the observation times of an airborne or spaceborne synthetic-aperture radar (SAR) system to effect the maximum coverage of a specified area (denoted the target), given a...

Optical oscillators that exploit resonantly enhanced four-wave mixing in nonlinear whispering-gallery-mode (WGM) resonators are under investigation for potential utility as low-power, ultra-miniature sources of stable, spectrally pure microwave signals. There are numerous potential uses for such oscillators in radar systems, communication systems, and scientific instrumentation. The resonator in an oscillator of this type is made of a crystalline material that exhibits cubic Kerr nonlinearity,...

A proposed method of surgical repair of fractured bones would incorporate recent and future advances in the art of composite materials. The composite materials used in this method would be biocompatible and at least partly bioabsorbable: that is, during the healing process following surgery, they would be wholly or at least partly absorbed into the bones and other tissues in which they were implanted. Relative to the traditional method, the proposed method would involve less surgery, pose less...

A phase sensor has been developed for use in aligning a segmented telescope mirror to within a fraction of a wavelength in piston. (As used here, piston signifies displacement of a mirror segment along the optical axis of the telescope.) Such precise alignment is necessary in order to realize the full benefit of the large aperture achievable through segmentation. This phase sensor is achromatic. It is based on two-wavelength shearing interferometry, and can be modified to utilize an extended or...

A document discusses lightweight instrument booms under development for use aboard spacecraft. A boom of this type comprises a thin-walled graphite fiber/ matrix composite tube with an integral hinge that can be bent for stowage and later allowed to spring back to straighten the boom for deployment in outer space. The boom design takes advantage of both the stiffness of the composite in tubular geometry and the flexibility of thin sections of the composite. The hinge is formed by machining...

The primary objective of this project is to understand the consequences of glow electrical discharges on the chemistry and biology of Mars. The possibility was raised some time ago that the absence of organic material and carbonaceous matter in the Martian soil samples studied by the VikinG Landers might be due in part to an intrinsic atmospheric mechanism such as glow discharge. The high probability for dust interactions during Martian dust storms and dust devils, combined with the cold, dry...

The Nation uses water-level data for a variety of practical purposes, including hydrography, nautical charting, maritime navigation, coastal engineering, and tsunami and storm surge warnings (NOAA, 2002; Digby et al., 1999). Long-term applications include marine boundary determinations, tidal predictions, sea-level trend monitoring, oceanographic research, and climate research. Accurate and timely information concerning sea-level height, tide, and ocean current is needed to understand their...

A prototype external-cavity diode laser (ECDL) has been developed for communication systems utilizing dense wavelength- division multiplexing (DWDM). This ECDL is an updated version of the ECDL reported in Wavelength-Agile External- Cavity Diode Laser (LEW-17090), NASA Tech Briefs, Vol. 25, No. 11 (November 2001), page 14a. To recapitulate: The wavelength-agile ECDL combines the stability of an external-cavity laser with the wavelength agility of a diode laser. Wavelength is modulated by...

Theodolite ring lights have been invented to ease a difficulty encountered in the well-established optical-metrology practice of using highly reflective spherical tooling balls as position references. A theodolite ring light produces a more easily visible reflection and eliminates the need for an autocollimating device. A theodolite ring light is a very bright light source that is well centered on the optical axis of the instrument. It can be fabricated, easily and inexpensively, for use on a...

The term "virtual feel" denotes a type of capaciflector (an advanced capacitive proximity sensor) and a methodology for designing and using a sensor of this type to guide a robot in manipulating a tool (e.g., a wrench socket) into alignment with a mating fastener (e.g., a bolt head) or other electrically conductive object. A capaciflector includes at least one sensing electrode, excited with an alternating voltage, that puts out a signal indicative of the capacitance between that...

Arrays of nanowires having controlled dimensions can now be fabricated on substrates, optionally as integral parts of multilayer structures, by means of a cost-effective, high-yield process based on ion milling on steps. Nanowires made, variously, of semiconductors or metals are needed as components of sensors and high-density electronic circuits. Unlike prior processes used to fabricate nanowires, the present process does not involve electron-beam lithography, manipulation of nanoscopic...

A computer program called "Rational Sequence" generates Universal Modeling Language (UML) sequence diagrams of a target Java program running on a Java virtual machine (JVM). Rational Sequence thereby performs a reverse engineering function that aids in the design documentation of the target Java program. Whereas previously, the construction of sequence diagrams was a tedious manual process, Rational Sequence generates UML sequence diagrams automatically from the running Java code.

Filters that suppress electromagnetic interference (EMI) on signal cables connected to cryogenic electronic equipment can be made from cores consisting of high-permeability materials. The basic principle of operation of these filters is the same as that of the ferrite-core common-mode EMI filters now commonly used on cables that connect computers with peripheral equipment. An inductive EMI filters blocks EMI due to its impedance to high frequency EMI signals. Since the impedance is proportional...
